AI Finally Translated The Voynich Manuscript — It Isn't A Language At All
Main summary
Key takeaways
Scientific concepts, discoveries, and nature/phenomena discussed
Origin, physical dating, and artifact verification
- Radiocarbon dating of vellum (University of Arizona, 2009) established the manuscript’s writing material dates to roughly 1404–1438, supporting that it is an early-1400s artifact rather than a modern forgery.
- The manuscript contains:
- ~240 surviving pages (believed originally closer to ~272)
- Invented script (no matching known alphabet)
- Unidentified plant illustrations
- Unfamiliar star-chart constellations/sky drawings
- Human figures with unclear interpretation
Handwriting / textual production hypotheses
- Paleography (researchers who study handwriting) suggests the text may have been produced by multiple scribes using a shared invented alphabet, inferred from consistent letter-shape habits across pages.
Computational/AI language identification claims and critiques (2014–2017)
1) “Plant/constellation word readings” via a historical-pattern matching method (2014)
- Stephen Bax (2014) proposed partial readings by borrowing a method used in ancient Egyptian hieroglyph decipherment:
- Start from proper-name-like elements
- Expand outward to other symbols using associations with nearby illustrations
- Reported tentative matches (as stated in subtitles):
- Plant names including juniper and coriander
- Possible constellation association: Taurus
- Criticism:
- Other researchers argued the method was open-ended and could fit many language families (not a strong language-unique decipherment).
2) AI “Hebrew” detection using alphagram/anagram-style scrambling (2017)
- Core idea: Voynich words might be alphagrams—letters rearranged into alphabetical order (with vowels removed in the proposed interpretation).
- Training/validation step (NLP test unrelated to Voynich at first):
- Train on the Universal Declaration of Human Rights translated into 380 languages
- Shuffle letters within each word into alphabetical order
- Test whether the model can still identify the source language
- Reported performance: ~97% correctly identifying language
- Application to Voynich text:
- The system ranked Hebrew highest among candidates.
- Multiple languages were considered, but Hebrew was flagged most likely.
- Major critique:
- The translated output required manual spelling corrections and Google Translate to become coherent.
- Medieval-language experts argued an algorithm trained on modern languages cannot reliably infer the language of a 1400s technical text; reliance on translation tools reduces credibility.
- Researchers emphasized they did not have a full, proven decipherment.
Statistical tests for “does it behave like language?”
These approaches do not claim a specific translation, but test whether the text’s statistical structure resembles natural language rather than random noise or artificial word generation.
1) Hidden Markov model to map two writing “styles” (2011)
- Kevin Knight & Shravana Reddy (2011) used a hidden Markov model (HMM):
- Goal: classify each page as leaning toward Currier “Language A” vs “Language B”
- Result: the model generated a page-by-page style-strength map
- Correlation: Language A dominated herbal sections; Language B dominated biological/recipe sections.
- Additional key observation:
- Low entropy in letter patterns (predictable letter ordering relative to real languages like English/Latin), dividing researchers into:
- those who view it as evidence of an unusual but real language
- those who view it as a warning of artificial text generation
- Low entropy in letter patterns (predictable letter ordering relative to real languages like English/Latin), dividing researchers into:
2) Information-theoretic “network” clustering of content words (2013)
- Marcelo Montemurro et al. (PLOS ONE, June 2013) treated the manuscript as a network of connected words.
- Information theory claim:
- In natural languages, content words (nouns/verbs) show strong clustering around topics and act like network “hubs,” while small connector words distribute more evenly.
- Result:
- Voynich word usage patterns were reported as compatible with meaningful language (not random gibberish), without proving specific semantics.
3) Multi-test statistical physics comparison to real languages (2013)
- Diego Amancio et al. (PLOS ONE, 2013) compared Voynich against a large corpus of confirmed human languages using three tests:
- Zipf’s law (frequency distribution: few words very common, most rare)
- Complex network shape of word relationships
- Time-series-like repetition tracking across page order (pattern of word recurrence/clustering)
- Result:
- The manuscript’s statistics fell within ranges produced by real languages, not random noise.
- Limitation:
- The framework could not identify which language or prove hidden meaning.
4) Large-scale entropy/character predictability comparison using Wikipedia corpora (2020)
- Luke Lindemann & Claire Bowern (2020) scaled comparisons using:
- Cleaned Wikipedia text across many modern languages
- A separate historical multilingual collection spanning centuries
- They measured conditional character entropy:
- predictability of a letter given the preceding letter(s)
- Result:
- Voynich characters had unusually low entropy (more predictable than normal English/Latin-like patterns in tested corpora).
- Important nuance:
- Certain real encoding methods—especially those using bigraphs (two letters combined into one symbol)—can also drive entropy down into a similar low range.
- Interpretation offered: if real language exists beneath, it may have been processed through unusual encoding.
Physical “earlier attempt” evidence (2024)
- Lisa Fagan Davis (2024) analyzed multispectral images (from the earlier Lazarus Project).
- Discovery:
- Faint margin notes containing a string of Roman letters.
- Interpreted as likely left by someone attempting an early decipherment.
- Significance:
- Confirms the manuscript has been treated seriously as a solvable puzzle long before modern computational methods.
Competing “not a real language” generation theories (mechanical/algorithmic hoax models)
1) Cardan grille + syllable tables generator (Cryptologia; researcher Gordon Rugg)
- Gordon Rugg (Keele University) proposed a 15th-century-capable low-tech mechanical generation:
- Cardan grille (masking/reveal pattern device)
- Pre-made tables of word-building syllables
- Claim:
- One could generate endless plausible-looking invented words without encoding meaningful hidden language.
- Rugg (2016 follow-up):
- argued the method could reproduce several statistical “fingerprints” identified by earlier computational studies.
2) Self-referencing mechanical word construction (Cryptologia; Torsten Timm & Andreas Schinner)
- Torsten Timm & Andreas Schinner proposed a mechanism where:
- new words are built from pieces of previously written words
- identified from how word spellings repeat/shift across the manuscript
- Claim:
- Statistical patterns could arise as byproducts of mechanical generation, not real semantics.
Examples of overhyped/unverified “AI solved it” claims (warning about methodology)
- Gerard Cheshire (University of Bristol, 2019): claimed “proto-romance” decipherment; quickly rejected and a press release was retracted within a day.
- Other viral claims (not peer-reviewed):
- “old Turkish”
- astrology/medical treatment interpretations attributed to a specific monk
- The subtitles emphasize these claims lacked peer-reviewed publication and independent reproducibility.
Lists / methodology outlines (as presented)
Kondrak & Hauer (2017) alphagram-style NLP pipeline
- Train an NLP classifier on Universal Declaration of Human Rights translations in 380 languages
- Create scrambled training/evaluation inputs by:
- shuffling letters within each word into alphabetical order
- Validate:
- evaluate ability to identify source language despite within-word scrambling (~97% reported)
- Apply the trained system to the Voynich manuscript text
- Interpret the top-ranked language as the likely source under the alphagram hypothesis (Hebrew reported)
Knight & Reddy (2011) hidden Markov model classification
- Use a hidden Markov model over a transcribed version of the manuscript
- Goal:
- assign each page a probability/strength of belonging to:
- Currier Language A
- Currier Language B
- assign each page a probability/strength of belonging to:
- Output:
- a page-by-page statistical map matching herbal vs. other sections
- Additional analysis:
- observe low entropy in letter/pattern behavior
Montemurro et al. (2013) information-theoretic word network test
- Represent manuscript as a word network (connected words)
- Use tools from information theory
- Compare network behavior to expectations from real languages:
- meaningful content words cluster/hub around topics
- connector words distribute broadly
- Conclusion framed as:
- patterns compatible with meaningful language, not random noise
Amancio et al. (2013) statistical physics comparison set
- Compare Voynich vs. large corpora of known human languages using:
- Zipf’s law
- complex network structure
- sequential/repetition “time series” behavior
- Conclude:
- Voynich lies within statistical ranges typical of real languages, not random noise
- Limitations emphasized:
- cannot identify language or prove hidden semantic content
Lindemann & Bowern (2020) conditional character entropy scaling
- Build multilingual corpora from:
- Wikipedia (modern languages)
- historical text collections
- Compute conditional character entropy:
- how predictable a letter is given preceding context
- Compare Voynich distribution to corpora
- Note encoding hypothesis:
- encoding methods like bigraphs can yield similarly low entropy

Video topic takeaway (“scientific standing” as described)
- The manuscript is treated as a real early-1400s artifact, with multiple computational studies showing statistical compatibility with natural language behavior, while multiple mechanical-generation and decoding critiques argue those statistical signals could be produced without real underlying meaning.
- No approach described in the subtitles yields a confirmed translated sentence accepted by the wider expert community.
